Hello. A few days ago I have upgraded from MediaWiki 1.5.8 to 1.6.7. I am running PHP 5.2.0-dev (nighly build as of 29 June 2006, 22:30 UTC), MySQL 4.1.13a and Apache 2.2.2 under Windows XP SP2. Some time after upgrading, I realised that history pages were empty. The history for the main page looks like this, with "Latest", "previous 50" and all the records-per-page selectors linked: --- (Latest | Earliest) View (previous 50) (next 50) (20 | 50 | 100 | 250 | 500). Diff selection: mark the radio boxes of the versions to compare and hit enter or the button at the bottom. Legend: (cur) = difference with current version, (last) = difference with preceding version, M = minor edit. (Latest | Earliest) View (previous 50) (next 50) (20 | 50 | 100 | 250 | 500). --- However, the database seems to be ok. Viewing diffs from Recent Changes page, as well as the Recent Changes themselves, works as expected, and no data seems to have been lost. I would like to know if anyone knows how to solve that problem. Thanks, Eduardo
